What is the volume of a circle formula?

A circle, being a plane figure, has no volume.The volume of a circle is a big fat ZERO.

It's a 2D figure, it cannot have volume.

Volume of a sphere = 4/3 * pi * r^3
Here are the volumes of figures that circles are a part of.

Sphere : (4 * pi * cube of the radius)/3
Hemisphere: (2 * pi * cube of the radius)/3
Cylinder: pi * (square of the base radius) * height
Cone: (pi * square of base radius * height)/3

The area of a circle is (pi * square of the radius).

Similarly you can find The Distance Formula and can solve it .

An interesting fact about circles is that the ratio between their circumference and their diameter is always the same, no matter what size the circle is. That ratio is given the name pi ( π ) and has the value of 3.141592+. Pi is an irrational number. That is, it cannot be expressed as the ratio of two whole numbers. The + added at the end of the value above means that the value of pi is indeterminate: you can continue to divide the circumference of any circle by its diameter forever and never get an answer without a remainder. The area of any circle is equal to its radius squared multiplied by π , or: A = π r 2 . The circumference of a circle can be found by multiplying its diameter by π (C = π D) or twice its radius by π (C = 2πr).

Circle does not has any volume it only has area. Probably you would be asking for volume of sphere. It is V= 4/3*pi*r^3.

A=πr² is the formula for Area of Circle.

Also that page makes the assertion that "pi ([tex]\pi[/tex]) equals 22/7 or 3.14". Those are approximations to [tex]\pi[/tex], not its actual value (and 22/7 is not equal to 3.14!).
